File handling in mfc's(previous record)

[rajeswaridevi]

Hi,
How to access the previous record from a file in MFC's.
For example we are reading data from a file and after reading some records if we want to read the previous record, then how can we to this.
and how can we directly read the last record from the file.
If we use SeekToEnd() we are going to the end of the file and not able to read the last record.
Even I am not able to read the file record by record.For that I am reading the file upto a new line character occurs and then using Seek to move the pointer.
Here I am assuming each line as a new record.
Please help me.Give some examples.
Thank you.

What do you mean by "record"?

You cannot do this if you have a variable record size (i.e. number of bytes in the record). Otherwise if you have a fixed record size (i.e. each record containing a predefined number of bytes), then you can supply the bytes offset to find a particular record and read.

I think you are assuming a line read from file as a record :-?
what are trying to do ?

HI,
Here I am assuming each line as a new record. And each line is of vaiable length.
